Display shows AL and an alarm sounds intermittently, even though the freezer seems to be cooling normally.

Safety: Unplug the freezer before removing door switch components.

Steps to fix AL (door alarm):

• 1. Check door closure: Ensure the door or lid closes fully and evenly. Look for items or baskets preventing a tight seal.
• 2. Inspect door switch: Locate the door switch (usually a small plunger switch in the frame or a magnetic reed switch). Press it manually; the interior light should turn on/off accordingly.
• 3. Test switch continuity: With the freezer unplugged, remove the switch and test it with a multimeter. It should open and close reliably when pressed/released.
• 4. Check magnet alignment: On models with a magnetic reed switch, ensure the magnet in the door aligns correctly with the switch in the cabinet. Adjust or resecure if loose.
• 5. Replace faulty switch: Install a new New World door switch if the old one is intermittent or open circuit.
• 6. Wiring and PCB: If the switch is good but AL persists, inspect the wiring back to the main control PCB. A PCB input fault may require board replacement.

Tip: A faulty door switch can also prevent the evaporator fan from running (on some models), affecting cooling.
